On POWER6 and POWER7 if the input operand to an instruction is a denormalised single precision binary floating point value we can take a denormalisation exception where it's expected that the hypervisor (HV=1) will fix up the inputs before the instruction is run. This adds code to handle this denormalisation exception for POWER6 and POWER7. It also add a CONFIG_PPC_DENORMALISATION option and sets it in pseries/ppc64_defconfig. This is useful on bare metal systems only. Based on patch from Milton Miller. Signed-off-by: NMichael Neuling <mikey@neuling.org> Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

This patch creates a new submenu for the NX cryptographic hardware accelerator and breaks the NX options into their own Kconfig file under drivers/crypto/nx/Kconfig. This will permit additional NX functionality to be easily and more cleanly added in the future without touching drivers/crypto/Makefile|Kconfig.

When looking through some instruction traces I noticed our tracepoint checks were inline. It turns out we don't have CONFIG_JUMP_LABEL enabled. By enabling CONFIG_JUMP_LABEL we replace a load/compare/branch with a nop at every tracepoint call. For example in do_IRQ: CONFIG_JUMP_LABEL disabled: stdx 3,11,9 lwz 0,8(29) cmpwi 7,0,0 bne- 7,.L124 bl .irq_enter CONFIG_JUMP_LABEL enabled: stdx 3,11,9 nop bl .irq_enter Signed-off-by: NAnton Blanchard <anton@samba.org> Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

The ns_cgroup is an annoying cgroup at the namespace / cgroup frontier and leads to some problems: * cgroup creation is out-of-control * cgroup name can conflict when pids are looping * it is not possible to have a single process handling a lot of namespaces without falling in a exponential creation time * we may want to create a namespace without creating a cgroup The ns_cgroup was replaced by a compatibility flag 'clone_children', where a newly created cgroup will copy the parent cgroup values. The userspace has to manually create a cgroup and add a task to the 'tasks' file. This patch removes the ns_cgroup as suggested in the following thread: https://lists.linux-foundation.org/pipermail/containers/2009-June/018616.html The 'cgroup_clone' function is removed because it is no longer used. This is a userspace-visible change. Commit 45531757 ("cgroup: notify ns_cgroup deprecated") (merged into 2.6.27) caused the kernel to emit a printk warning users that the feature is planned for removal. Since that time we have heard from XXX users who were affected by this. Signed-off-by: NDaniel Lezcano <daniel.lezcano@free.fr> Signed-off-by: NSerge E.

The pseries and ppc64 defconfigs have drifted apart over the years.

Now we have high res timers there is less of a reason for a high HZ value. Furthermore I think there a few reasons we should reduce HZ to 100: - Timer interrupt overhead. While this overhead is small, there are applications that are very sensitive to jitter (eg some HPC apps). - Issues with the timer wheel code. When coming out of NO_HZ idle we work our way through the timer code one tick at a time. If we have been idle a long time, this adds up - I sometimes see milliseconds of time spent in that loop. Long term we should fix the timer wheel algorithm, but for now if we reduce HZ then we reduce the amount of work the timer code has to do when coming out of idle.

When checking out the new NO_HZ support in powerpc, I noticed we never slept for more than 2 seconds. It turns out SLAB has a 2 second per cpu timer that causes this. After switching to SLUB I see some nice 4 second sleeps which is the limit on this POWER6 box (the decrementer ticks at 512MHz): slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 3.96 sec slept 3.80 sec slept 2.99 sec Since SLUB is now the default and some powerpc defconfigs already enable it, lets enable SLUB across the board for consistency. While doing this I also noticed that the maple defconfig has SLAB debugging enabled which is sure to make your box nice and slow. Fix that too.
